But special forces are sufficiently bad-ass that they might go undetected, and be able to slip into town, if they were not especially taller than their competition.

So it is a totally different sort of story.

And Augustus was no fool. He likely understood logistics from a roman viewpoint very well. Also, Augustus was seen as a good protector of Rome. He was the guy who originally had the title of "Prince of Peace" etc. Not that Jesus fellow.

They MIGHT be able to hide, but that they could take down the whole Roman Empire seems far fetched. It's changed the entirety of the story, the movie isn't going to be anything like the story that started this subreddit.

No if they went in and took out Caligula or Nero, they would likely have a bit more support.

And I would not put it past a special forces team to have someone who was an expert in latin, because it would be a badass hobby to have. (reading Ceasar in the original latin, just for the insight into the military mind sort of thing)
